            <div id="ConfluenceContent"><p>The framework provides several access helpers to access Session, Application, Request scopes.</p>

<h2 id="Accessingapplication,session,requestobjects-AccessingfromJava">Accessing from Java</h2>

<p>All the JEE scope attribute maps can be accessed via <code>ActionContext</code>.</p>

<div class="code panel pdl" style="border-width: 1px;"><div class="codeHeader panelHeader pdl" style="border-bottom-width: 1px;"><b>Accessing servlet scopes</b></div><div class="codeContent panelContent pdl">
<pre class="brush: java; gutter: false; theme: Default" style="font-size:12px;">
Map attr = (Map) ActionContext.getContext().get("attr");
attr.put("myId",myProp);

Map application = (Map) ActionContext.getContext().get("application");
application.put("myId",myProp);

Map session = (Map) ActionContext.getContext().get("session");
session.put("myId", myProp);

Map request = (Map) ActionContext.getContext().get("request");
request.put("myId",myProp);
</pre>
</div></div>

<div class="confluence-information-macro confluence-information-macro-warning"><span class="aui-icon aui-icon-small aui-iconfont-error confluence-information-macro-icon"></span><div class="confluence-information-macro-body">
<p>Do not use <code>ActionContext.getContext()</code> in the constructor of your Action class. The values may not be set up, and the call may return null for <code>getSession()</code>.</p></div></div>

<p>We can also access the <code>HttpServletRequest</code> and <code>HttpServletResponse</code> objects themselves through <code>ServletActionContext</code>. In general this isn't recommended as it will tie our action to the servlet specification.</p>

<div class="code panel pdl" style="border-width: 1px;"><div class="codeHeader panelHeader pdl" style="border-bottom-width: 1px;"><b>Setting session attribute through session object</b></div><div class="codeContent panelContent pdl">
<pre class="brush: java; gutter: false; theme: Default" style="font-size:12px;">
ServletActionContext.getRequest().getSession().put("myId", myProp);
</pre>
</div></div>

<p>Implementing <code>ServletRequestAware</code> or <code>ServletResponseAware</code>, combined with the <code><a shape="rect" href="servlet-config-interceptor.html">"servletConfig" interceptor</a></code>, is an alternative way to access the request and response objects, with the same caveat.</p>

<h2 id="Accessingapplication,session,requestobjects-Accessingfromtheview(JSP,FreeMarker,etc.)">Accessing from the view (JSP, FreeMarker, etc.)</h2>

<p>Request and session attributes are accessed via OGNL using the <code>#session</code> and <code>#request</code> stack values.</p>

<p>The <code>#attr</code> stack value will search the <code>javax.servlet.jsp.PageContext</code> for the specified key. If the <code>PageContext</code> doean't exist, it will search the request, session, and application scopes, in that order.</p>
